So I just downloaded a Network Sniffer on my local machine, as I think something is going on.
As soon as I opened it, selected my network adapter (an LTE stick), it started showing me requests from Chrome to s*.crdui.com (where * represents a 821 or 1821, for example: s1821.crdui.com).
Having looked around the web, it seems that it isn't dangerous, but nothing can tell me what it is.
This is the packet information for one of the many requests:
Just to clarify, if the subdomain is
s1821, then the request path is always
/related. If the subdomain is
s821, then the request path is always
I'm running Windows 8.1.
And I know that Chrome is doing it, because the sniffer tells me the User Agent String for the request - in my case, it is:
Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36
Does anyone have any idea what this is, and if it isn't such a good thing?
